Première consultation sans frais avec un technologue en architecture pour valider la faisabilité de votre projet

In the heart of the cobbled streets of Quebec, the art of home restoration evolves like a meticulously orchestrated ballet.


The houses, guardians of architectural heritage, are being given a second lease of life through a multitude of renovation projects.


Over the course of a captivating page, we will dive into the world of residential transformations, where three major themes emerge: the elevation of houses towards new horizons with the addition of floors, the expansion of habitable space by daring enlargements and finally, the infinite range of other types of restorations which redefine the limits of possibility.

Renovation plan:
For a floor addition



Before starting anything, make sure that the project meets all the construction standards of the city and the building in question, with the town planning department of your municipality.

This includes building height regulations, building codes and zoning requirements.

If necessary, your technologist will be able to enlighten you on this subject during your first free consultation.


Our firm's technologists perform a detailed assessment of your existing property to determine its structural and aesthetic feasibility for a floor addition.


This phase involves a thorough analysis of the foundation, load-bearing walls and other structural elements.


Once feasibility is established, our technologist will work closely with you to create detailed plans of the new floor configuration created.


This includes room layout, materials to be used, and aesthetic considerations.

To help him, you can provide him with your existing house plans, photos of the rooms which will be affected by the work, emphasizing the areas which will be modified and sketches or examples of what you want to do in your home so that he can make you a proposal adapted to your needs.


He will then come to take the measurements of your house, locate where the windows, doors are, know everything that is necessary and which may have changed between your current house plans and its final construction. This is when he will draw up your plans.


After submitting your plans, you will be able to return to your municipality to apply for a building permit.


If necessary, we help obtain building permits and other approvals required by local authorities. This ensures that your project is legally compliant.


This phase includes the actual construction of the added floor. At this point you will be able to contact a contractor to plan and begin construction, with final plans provided by our architectural technologist. 


If necessary, we can suggest partner contractors with whom we are used to working and recommend.


Finally, the last stage of your project arrives: the work.


And if you want to reduce your costs as much as possible and stay within your budget, you can first meet with a construction estimator who will help you choose in advance what type of finishes you want.ite use like plumbing, flooring, bath, etc. It will help you know the current materials market and perhaps revise your choices downward to stay within your budget and have a clearer price in mind.

By calling on us, you are assured of receiving quotes with precise estimates after an initial evaluation of your property and a discussion on your needs and preferences, all with the aim of offering you the best price to carry out your work. construction. It is important to consider not only the construction costs, but also the prices associated with permits, approvals and possible structural modifications necessary to the rest of the house, cottage or garage.

The return to investment

A well-designed and executed floor addition can have a significant impact on the value of your property. Homes with more living space tend to sell for higher prices. However, the return on investment will also depend on local real estate market conditions and the quality of project execution.
